Senior Software Engineer - IoT

About The Role

As a Senior Software Engineer (f/m/d), you will be part of a high‑impact team designing and enabling our GROPYUS Smart Living and Smart Building experience through scalable systems. You will design and operate the technical backbone of our smart buildings.
